Abstract
This work is concerned with the temporal characteristics of event-related b lood oxygenation level-dependent (ER-BOLD) and visual-evoked potential (VEP ) signals produced by checkerboard stimulation of human V1, The study inves tigated whether different control features produce different amplitude VEPs , and if so, whether this corresponds to different ER-BOLD responses. The r esults showed that there was a difference in the amplitude of the P1-N1 com ponents of the VEPs, and also in the magnitude and extent of the ER-BOLD re sponses. These results suggest the possibility that the P1-N1 components ma y be related to the difference in the magnitude and extent of the ER-BOLD r esponse.
